Use dotenv and provide example

[andersevenrud]

Split out from #742

It would be nice to use dotenv by default to allow overriding the very basic foo/config.js defaults, as well as a .env.example for reference.

This could probably also contain the docker-composer variables as well.

I added a section about this in the manual. So I'm closing this issue.

os-js/manual.os-js.org@3ed7080

Since I'm doing some passes on the manuals at this moment this will get better documented.

hi @andersevenrud.
I want to manually set the parameters in the server and client config files through the . env are initialized.
So I have added the .env file to the project.
I have used it in the server configuration file as follows.

require('dotenv').config();
module.exports = {
  root,
  port: process.env.PORT,
  public: path.resolve(root, 'dist'),
}

I have also used the following in the client config file.

import 'dotenv/config';
export default {
  session:{
    timeout: process.env.CLIENT_SESSION_TIMEOUT
  },
}

But in the client, I get the value of timeout parameter as undefined.

Didn't you solve this here os-js/osjs-client#208 ?

Hm. Come to think of it you probably might have to add a Webpack plugin. Try https://github.com/mrsteele/dotenv-webpack, but with an older version (6.x.x) for the webpack used here.

The standalone dotenv package probably won't work here.

This issue os-js/osjs-client#208 was for use in Docker.
Here is the question for developer mode.
